Title: Energy absorption device
Inventor: PENTELOW TONY
IPC: F16F7/12
Filed: 1985-05-28
Abstract: An energy absorption device comprises a sacrificial member 10, 11 of fibre reinforced plastics material, and a rigid element 13 which shears through the sacrificial member to absorb energy when a moving mass impinges on the device. The device may be in the form of a telescopic strut with two nesting tubes 10, 11 through which there is drilled a hole 12 in which there is received a pin 13. The tubes are of fibre reinforced plastics material whereas the pin is of stiffer material, such as, metal. When the strut gives way under a loading (P), the pin is forced to shear through the tube material. Alternatively, a fibre reinforced plastics tube may be forced through a metal sleeve bearing radially inwardly facing pins. To absorb tensile loads, a pin could be pulled through a sheet of fibre reinforced plastics material. Examples are given of the plastics, and of the material, formulation, and disposition of the fibres. <IMAGE>

Title: Container closure handling mechanism
Inventor: WATERWORTH PHILIP DAVID
IPC: B65B7/28
Filed: 1986-07-04
Abstract: A mechanism for removing a closure C from and replacing that closure on a container B during a container filling operation comprises a gripping assembly 2, which is actuable to grip the closure and is shiftable by hydraulic motor 13 so as to move a gripped closure between spaced apart positions where the closure is partially fitted to the container and is removed from the container.

Patent GB-2243716-A (GB)
Title: Self-aligned, planar heterojunction bipolar transistor and method of forming the same
Inventor: CLARK MARION D
IPC: H01L21/331
Filed: 1989-10-31
Abstract: The transistor is formed with self-aligned base-emitter 6, 4 and base-collector 6, 8 junctions by forming a two-level mask (Fig 4) over a doped base layer, sequentially forming openings in registration (Figs 4, 5) through the two mask layers, and using the opening in one mask layer to define the collector region 8 and the opening in the other mask layer to define the emitter base 6. A buried conductive layer (16 Fig 3) formed by a dopant implant establishes an electrical contact to the collector region and connects to the surface via another conductive implant (20 Fig 3) that extends through a lateral extension of the collector region. The collector region itself is formed by a high energy silicon dopant implant, while the active base region which forms junctions with the emitter and collector is etched thinner than the remainder of the base layer. The latter feature reduces the resistivity associated with connections to lateral base contacts. Parasitic capacitances are minimized when the collector and buried conductive layers are implanted into a semi-insulating substrate such that only the active junction regions overlap, enabling high speed operation. The collector (24) and emitter (32) contact regions are opposite each after (Fig 1), the base contact regions (26) being lateral to them both. <IMAGE>
